criminalapplication med June 7, 1926, Serial No. 114,361. Divided and this application filed. June 20,

1927. Serial No. 200,079.

This invention relates generally to door handle assemblies and refers more particularly to the attachment of such assemblies to vehicle doors.

An object of the invention is to provide a door handle assembly in which the lock is anchored in such a manner that it would be practically impossible for an unauthorized person to remove the lock to gain access to it) the inside of the vehicle.

With these and other objects in view, the invention resides in certain novel features of construction, combinations and arrangements of parts as will be more fully described and particularly pointed out in the appended claims.

lln the accompanying drawings:

Figure 1 is a longitudinal sectional view of my handle assembly.

Figure 2 2 is a section pillar showing the handle assembly secured thereto.

Figure 3 is a section through a wooden pillar showing a modification of Figure 2.

Figure 4 is a cross section of an all metal pillar construction showing the handle assembly secured thereto.

Referring now to Figure 1 of the drawing, there is shown a door handle assembly 1 consisting of an outer shank 2 of hollow tubular formation having the inner end thereof reduced as at 3 to receive a solid spindle 4, this spindle being preferably secured to the shank by a welding operation.

A detailed description of ,the handle assembly will not be given herein as such an assembly forms the subject matter of my 00- pending application Ser. No. 114,361 filed June 7 1926, the present application being a division thereof. Therefore only those elements which are essential to the present invention will be enumerated herein.

Upon the shank 2 is rigidly mounted a handle tube 5 against which a loosely mounted escutcheon plate 6 is adapted to abut. The shank is loosely mounted in a base plate 7 and as shown is adapted to be enclosed by the escutcheon plate 6. The inner end of the shank 2 also supports a cup-washer 8 while a coil spring 9 is adapted to encircle the shank between the washer 8 and base through a wooden plate 7 and tends to retain the base plate against the inner surface of the escutcheon p a e.

As will be noted, a standard lock cylinder 10 is retained within the shank 2 and is so Mounted on the spindle a is a flat washer 15 secured thereto in any suitable manner and when the handle is inserted in the transverse bore, this washer will engage the shoulders let and rest thereon, preventing any fur- YZher movement of the spindle within the ore.

It has been the practice in the past for unauthorized persons to unscrew the escutcheon plate so that it could be'pulled out free from the framework to gain access to the lock mechanism. The present construction has been designed to prevent the removal of the escutcheon plate and the subsequent tampering with the lock mechanism. As shown, this is accomplished by providing avscrew 16 that is screwed into the pillar so that the inner end thereof projects into the transverse bore just in advance of the washer 15, limiting the longitudinal movement thereof.

The base plate 7 is provided with recessed bosses 17 located on either side of the shank 2, while the escutcheon plate is provided with correspondin countersunk recessed portions 18 fitting into the bosses as shown in Figure 1. As will be noted, the bosses are substantially thick and are received in correspondingly deep recesses 19, located in the pillar 12. The thickness of the bosses as compared with the limit of movement of the washer is such that should an unauthorized person attempt to remove the escutcheon plate, the washer 15 would strike against the inner end of the screw 16 before the lar to that disclosed in Figure 2, with the exceptionthat amachine screw 20 provided with a squared end'21 is used in place of the wood screw shown in Figure 2.

In Figure/l an all metal pillar construction is disclosed. A metallic strip 22 is secured to the panel 23 in any suitable manner andis provided with depressed portions 24 corresponding to the recesses 19 for receiving the bosses 17. Projecting at right angles from the strip 22 is an integral flange 25 to which a nut 26 is rigidly'secured. A bolt 27 corresponding to the screws 16 and 20 is provided for engagement. with the nut to limit the movement of the spindle.

From the foregoing it will be apparent that an improved construction has-been provided which will greatly facilitate the assembling of the shank and lock mechanism of an'automobile door handle and also provide an arrangement of parts which wilLdiscourage tampering with the locking mechanism by an unauthorized person.

While it is believed that from the foregoing description, the nature and advantages of my invention will be readily apparent, 1 desire to have it understood that I do not limit myself to the specific construction herein shown and described and thatlsuch changes may be resorted to when desired as fall-within the scope of what is claimed.

What I claim as my invention is:

1. The combination with a door, of a handle assembly having a shank extending transversely of said door, a projection on said shank, an element supported by said door and disposed in substantially arallel relation to the projection on said s iank so as to be engaged thereby, for preventing the removal of said handle assembly from the .door.

2. The combination with .a door, of a handle assembly having a shank extending transversely of said door, a projection on said shank, and means for securing the handle assembly to the door including an element supported by said door and disposed in sub stantially parallel relation to the projection on said shank in advance thereof and adapted to be engaged thereby.

3. The combination with a pillar, of a handle assembly havin a shank extending transversely of said pi lar, a projection on said shank and an escutheon plate having .a projection engaging a recess in the pillar, and means for securing the handle assembly to the pillar including an element disposed in the pillar in substantially parallel relation to theprojection on said shank so as to be engaged thereby, the distance between said element and projection beingless than handle assembly having a shankextendingtransversely of said pillar, a washer on said shank and a base plate havin a boss engaging a recess in the pillar, an means for securing the handle assembly to the pillar in-, cluding a rotatable element disposed in the pillar, in substantially parallel relation to the washer aforesaid so as to be engaged \thereby, the distance'between said element and Washer being less than the length of the base plate boss, whereby the latter will be retained in the recess'in said pillar.

5. The combination with a pillar provided with a transversely extending bore enlarged at its outer end, of a handle assembly havlng a shank located in said bore, a projection on said shank seated in the enlarged portion of the bore, a base plate having a boss engaging a recess in the pillar, and means for securing the handle assembly to the pillar including an element disposed in the pillar and portion of the bore aforesaid in substantially parallel relation to the projection on said shank so as to be engaged therewith, the distance between said element and projection being less than the length of the base plate boss, whereby the latter will be retained in the recess in said pillar.

6. The combination with a pillar provided with a transversely extending bore enlarged at its outer end, of a handle assembly having a shank located in said bore, a projection on said shank seated in the enlarged portion of the bore, and a base plate having a boss engaging a recess in the pillar, said pillar being provided with a bore communicating with and extending substantially transverse to the enlarged portion of the said first mentioned bore, and means for securing the handle assembly to the pillar including an element disposed in said second mentioned bore and having an end projecting into the enlarged portion of the first mentioned bore in substantially parallel relation to the projection on said shank so as to be engaged thereby, the distance between said element and projection being less than the length of the base plate boss whereby the latter will be retained in the recess in said pillar.

7 The combination with a door, of a handle assembly having a shank extending transversely of said door, a washer secured to said shank, and means for securing the handle assembly to the door including a rotatable element removably supported in said door and disposed in substantially parallel relation to said washer so as. to be en aged thereby, forpreventing the removal 0 said handle assembly from the door.

8. The combination with a door pillar provided with a transversely extending bore enlarged at its outer end, of a handle assembly having a shank located in said bore, a projection on said shank seated in the enlarged portion of the bore, and meansfor securing the handle assembly to the pillar including an element disposed in the pillar and having an end projecting into the enlarged portion of the bore aforesaid in substantially arallel relation to the projection on said shank so as to be engaged thereb In testimony whereof I aflix my si nature.
